There are two reasons why an ad-free and spy-free version (Googei) of Google's main search results is important.
1) Search engines should not be tracking you and retaining this information indefinitely. Not only does Google scrape much of the web, but they keep records of what you search. If information about your searching is accessible by cookie ID or by your IP address, it is subject to subpoena. This is a violation of your privacy. You should not be leaving your fingerprints in Google's databases.
There are other proxies that can protect your privacy on the web. Almost all are general-purpose proxies that cloak all of your web activity behind an IP address that is not easily traced to your service provider. One is Anonymizer.com. A possible problem with this one is that the founder, Lance Cottrell, has connections with the FBI of the United States as well as with the Voice of America. It also costs money for a reasonable level of service. Another is Tor, which is much more secure. But it is also slow, because Tor is a complicated system that needs networks of volunteers to run server software. Juvenile surfers from video pirates to rogue Wikipedia editors tend to clog free services such as Tor, which slows them down even more. Since Googei does just one thing, it is fairly fast and simple.
2) Showing Google's results without their ads improves the internet. About 99 percent of Google's total revenue comes from ads, and these are ruining the web. Thousands of "Made for AdSense" domains are spewing garbage. Since these sites need content to trigger Google's ads, they steal it by scraping legitimate sites, or generate their own by purchasing junk from bulk writers. Meanwhile, click fraud is rampant.
That leaves us asking lots of Googei users for small contributions. Searchers who prefer Googei are protecting themselves as well as making a unique statement about important issues. Nothing else we know of is making the same points as effectively. Please donate to keep Googei available for your protection.
